' 10 bled, has all the advantages of a bow of one solid piece. g V v a As arule bows for use in archery are about as tallas the archer who uses them and'it'i's quiteinconvenient to carry sucha bow in an ordinary closed automobile, on a crowded streetcar, oromnibus, and it is even inconvenient to carry them on'the open street. For almost 100 years various kinds of jointed bowshave been attempted, but none of these have ever found universal favor because they werenot as satisfactory as the bows ofvone singlef'piece and archers prefer the moon.

venience caused by the long bow, rather than to use jointed bows of inferior quality.

Furthermore, the bows at present'used 1n archeryare quite long and cannot be stored conveniently in a trunk, and cannot be easily transported from placeuto place, and by J making the bow in two separate parts, which may be assembled together when desired, the how can be more easily carried as baggage, or transported. 5 v 1 Since the rear and front of the bow are of different contours, in, order .to secure the proper assembly of the two parts, it will be necessary to provide'a joint, in which the two parts will always fit together in the same relative position one to theother. a i In making a jointed'bow, the following things must be considered and are of importance in the order mentioned.

'1. Alignmeht-The back of the bow (the side away from the bow string) is usually different in contour than the belly, (the side next to the bowstring),'although this is not always the case. Consequently, a bow that is jointed in theyhandle should havesome arrangement that will secure the proper alignment of the two limbs when they ,are put together. Heretofore those using jointed each other.

bows have usually depended upon the eye for this adjustment, and had no means for holding thefbow in positive alignment. My in Vention entirely offsets this difficulty, and the, mere bringing together of the two limbs of the bow, inseating the ferrule properly, in sures absolute alignment of the limbs.

2, Compensation for wean-An all of the previouslyjointed bows there has been no arrangement for thetake-up of Wear. This is of vast importance as the joint has worn and become shaky, which creaks 'or gives when the bow is' drawn, or which for any *reason does not have the firm rigidity ofa solid piecc, ten ds' to disconcert the archer while Sl100tl1lg, with a consequent disastrous result v The construction; of the upon his score. tapered joint in my invention is such that wear is automaticallycompensated for and even in case, there isyeryfconsiderable space between the male andifemale ferrule, .any 'loosene'ss is. immediately" compensated for,

once thebow has been strung, becauseof the wedglngaction of the ends of thebow against 3. Anti-freeze "feaZure.+One great dif- V ficulty of all previous jointed bows has been. that if a close, tight fit is made, such as would be required to keep the ordinary jointed bow rigid, there is great danger of this joint ,iireezlng 0r- StlClflIlg so that it cannot be pulled'a'pa'rt. This also" frequently caused byrr'ist orfo'reign matter getting in the joint and preventing the ready separation ofthe two limbs. f The peculiar fact aboutsuch a frozen joint is that the ferrulescanfre uen tly be turned within each. other, yet'wil resist withdrawal. The construction of my invens tion is such that eyen a slight turn'o'f these ferrules will tend'to force themapart. No .7 otherj ointed how has ever had this advantage I and the lack of it has prevented many archers.

from using the convenient jointed bow.

4Q Strengthr llo be just assatisfactory as" a one piece bow, 'a jointedbow musthave equal strength atthe joint,('or handle) as that of-the one piece Weapon; The construction of my invention is such that the. joint is the strongest partjof thebowl This-ispar'ticw' larly' true becausethe diagonal'feature of the taken apart, are of approximately the length. In many jointed bows, one limb is considerably longer than the other when taken apart and in consequence, the bow, when taken down is considerably longer than half the length of the full bow. In many designs of jointed bows this difference is as much as eight or ten inches, very nearly oil setting the advantages of the take-apart feature.

The foregoing objects are accomplished by my'invention, which will be more'clearly understood after reference to the accompanying drawings, in which like parts are indicated by similar reference symbols throughout the several views,and inwhich, V

Figure 1 is 'adiagram, showing an archer, in dotted lines, holding a bow.

Fi ure 5 isa sectional elevation on a larqer 1:. scale, showlng one form of oint used 111 as- Qsembling the two arms of the bow.

Figure 6'shows a section along the line 66 of Figure 5, and'looking down.

Figure 7 shows a section alongthe line 77 of Figure 5, and looking down.

, Figure 8 shows a section along the line 8-8 of Figure 5, and looking down, and Figure 9 is a similar view to Figure 5, but shows a modified form of oint.

The bow A consists ottwo limbs connected together, so that the belly a of each limb will be next to thearcher and the back a will be furthest away from the archer. The

end of each limb might be provided with a suitable tip B which may be in the form of a ferrule notched as at 7) to engage a bowstring C, shown only in Figure 1.

in order to form a strong and firm oint,

:one of the limbs, as A is provided with a metal, cylindrical sleeve D firmly secured thereon, and, the other limb A is provided with a similar sleeve D, which fits snugly 1n the sleeve D, but has "its outer end cut away at an melme, as indicated atcl and (Z to form aplaneeurfacewiththe beveled face a? of the limb A", seeFigure 5. The other limb A? is provided with a simllar beveled face a so that when the parts are assembled in the position shown in Figure 5, there will be a firm joint made, and each limb of the bow cannot twist in its socket, but the desired alignment of the two limbs will be effected.

Thus when the parts are assembled, as shown in Figure 5, the bow will be ready for use, and yet the two limbs may be readily taken apart, as shown in Figure i.

Vfhile the sleeves D and D may beheated and shrunken the ends of the corresponding limbs of the bow, obviously they might be further held in place by one or more pins, such as E, shown in Figures 5, 7 and 9.

In Figure'9, I have shown a slightly different form of joint, in that, instead of having the ends of the limbs A and A beveled, as shown in Figure 5, there is a wedge, or tongue and groove engagement in which one limb A is provided with the wedge a which fits into a corresp'onding tapered groove i in the opposite limb A. In this case, the inner sleeve D would be inthe form of a hollow cylinder with V-shaped cuts therein, and not cut away diagonally, asshow'n. in Figure '5.

It will be seen that in either form of joint, when the two limbs of thebow are assembled inthe socket piece, the limbs willfbe inalignment throughout, and will'not require any line adjustment or twisting of the two limbs,

so as to get them in the proper alignment.

By having the abutting faces 01 the two limbs of the bow in beveled engagement, as

shown, the effect of the taut string, will tend to pull the'two members together and thus automatically hold the two limbs in the properadjustment, but will also automatically adjust the bow for wearat the abutting faces.

It will be obvious that the two'limbs of :thebow may be's'eparated, 'andput in a bag, or otherwise conveniently carried, and may be quickly assembled and the "bow string applied whenever it is desiredto use the bow.

lVhile I have shown'two preil'erred embodin ients of the inven'tion, it will be obvious that various changes might be made in the construction, combination and. arrangement'of parts, which could be used without departing from the spirit of my invention, and '1 do not mean to'limit the inventionto such details, except as particularly pointed out in the claims.
